Which of the following statements are true about the graph of f(x) = 6(x + 1)² -9?
check all of the boxes that apply.

a. the vertex is (1, -9).

b. the graph opens upward.

c. the graph is obtained by shifting the graph of f(x) = 6(x + 1)² up 9 units.

d. the graph is steeper than the graph of f(x) = x².

e. the graph is the same as the graph of f(x) = 6x² + 12x - 3.

explain your answer?

don't spam your answer, it's going to mark report.

if it's wrong answer and it's going to mark report as a "improper answer."

don't copy or paste answers from other sites, if you copied and that's going let the mark as a report called "plagiarism."

you!

B, D, E

Step-by-step explanation:

A. The vertex is (1, -9).

False.  The vertex is at (-1, -9).

B. The graph opens upward.

True.  The leading coefficient 6 is positive.

C. The graph is obtained by shifting the graph of f(x) = 6(x + 1)² up 9 units.

False.  It is shifted down 9 units.

D. The graph is steeper than the graph of f(x) = x².

True.  The absolute value of the leading coefficient |6| is greater than 1.

E. The graph is the same as the graph of f(x) = 6x² + 12x - 3.

f(x) = 6(x² + 2x + 1) - 9

f(x) = 6x² + 12x + 6 - 9

f(x) = 6x² + 12x - 3

True.

the answer will be the last one

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
